I'm looking for a simple audio editor that can handle stereo tracks. I do interviews using Skype and record them with Audio Hijack Pro, using the left channel for input and right channel for output. I use Fission to edit mono audio tracks but it seems it doesn't handle stereo tracks. Is that right? Is there another simple app like Fission that can do this? I want to be able to adjust the levels of the input and output individually.
